(02.03 mc) if you wanted to improve your cardiovascular endurance, which of the following would be the best option? increase the number of components you are working on during exercise. increase the amount of time in your 50 - 80% thr zone during exercise. increase the amount of weight you are using during exercise. increase the amount of resistance you are using during exercise.

Explanation:

Cardiovascular endurance is related to the efficiency of the heart, lungs, and blood vessels during sustained physical activity. Increasing the time spent in the 50 - 80% THR (Target Heart Rate) zone is a key factor in improving cardiovascular endurance. Resistance, weight, and component - related changes are more relevant to strength training or muscle - building rather than cardiovascular endurance.

Answer:

Increase the amount of time in your 50 - 80% THR zone during exercise.
